Behind the Seams: Stella McCartney's Parisian Party

With her dad dutifully by her side, Stella McCartney celebrated the opening of her new flagship store in Paris. "For a British designer to have a boutique here in Paris is pretty cool," said former Beatle Paul McCartney. Mingling were Stella's A-list attendees, such as Yves Saint Laurent's creative director, Stefano Pilati, and topnotch models Lily Donaldson and Lara Stone. The guests looked to be having a ball, and I can see why. Champagne + robots + fashion = fabulous fun. Click through to see more smiles and laughter.
